- SD indicates standard deviation; NS, nonsignificant; *P < .05; **P < .01; ***P < 0.001.
- DNP, depth of the nasopharynx; HNP, height of the nasopharynx; DOP, depth of the oropharynx; DHP, depth of the hypopharynx; SPL, soft palate length; SPT, soft palate thickness; and SPI, soft palate inclination.
